Abstract: A method for annotating points on a 2D image of a hand, includes capturing several images of the hand from different views; for each viewpoint, the hand is imaged using cameras including: one first 2D camera and one 3D camera; using a 3D engine for: creating a 3D hand representation from the 3D camera; considering a 3D model of an articulated hand with predefined annotation points; considering several 3D viewpoints of the hand; for each viewpoint considered: modifying the articulated hand to be superimposed with the 3D representation; considering a 2D image captured from the first 2D camera; superimposing the modified articulated hand on the hand captured on the 2D image; applying the annotation points of the modified articulated hand on the hand captured on the 2D image; and storing the 2D image with annotation on the hand
